煤田地质勘探工程监理特点分析

结合煤田地质勘探工程监理工作实际,对煤田地质勘探工程监理与建设工程监理进行了比较,认为煤田地质勘探监理与建筑监理程序基本相同,目的都是提高工程水平,规范工程。但煤田地质勘探专业性较强,与建设工程相比也有许多不同之处,故而有必要建立煤炭地质勘探工程监理规范以指导煤炭地质勘探工程监理工作。     

浅谈煤田地质勘探中煤质研究和评价的意义

通过我国煤田地质勘探中煤层煤质的分析,研究认为煤炭不仅是重要的能源,同时也是重要的化工原材料,长期以来在煤田地质勘探中侧重于煤炭资源的勘探,忽视了对煤质的分析研究,建议在今后的煤田地质勘探中加强对煤质的分析研究,为煤炭的综合利用提供必要的参数。

河北省煤炭资源有效供给能力分析

通过对河北省煤炭资源有效供给能力研究分析认为：河北省煤炭开发强度大，衰老矿井逐年增多使煤炭产能递减，探采比例严重失调导致新建井基地严重不足，煤炭资源供给形势严峻。根据河北省近年来的煤田地质研究和勘探成果，开发新的煤炭基地，老矿区外围及深部煤田勘探，北部地区普查找煤，白垩纪褐煤勘探及开发研究应该是今后煤炭地质勘查工作的重点。因此，煤炭资源勘探工作任务艰巨，有关部门应从能源安全保障的战略高度，来审视煤炭地质勘探工作。

应用人工放射性測井曲线求原煤灰分含量

用测井曲线求原煤炭分含量,是当前煤田地质勘探中的迫切任务之一。是开展无岩心钻进的重要前提。为此,我们在邵明及邢北勘探区,开展了应用人工放射性曲线,求原煤灰分含量的试验工作。

The terrestrial fauna of the Late Triassic Pant-y-ffynnon Quarry fissures,South Wales,UK and a new species of Clevosaurus (Lepidosauria: Rhynchocephalia)

Pant-y-ffynnon Quarry in South Wales yielded a rich cache of fossils in the early 1950s, including articulated specimens of new species (the small sauropodomorph dinosaur Pantydraco caducus and the crocodylomorph Terrestrisuchus gracilis), but no substantial study of the wider fauna of the Pant-y-ffynnon fissure systems has been published. Here, our overview of existing specimens, a few described but mostly undescribed, as well as freshly processed material, provides a comprehensive picture of the Pant-y-ffynnon palaeo-island of the Late Triassic. This was an island with a relatively impoverished fauna dominated by small clevosaurs (rhynchocephalians), including a new species, Clevosaurus cambrica, described here from a partially articulated specimen and isolated bones. The new species has a dental morphology that is intermediate between the Late Triassic Clevosaurus hudsoni, from Cromhall Quarry to the east, and the younger C. convallis from Pant Quarry to the west, suggesting adaptive radiation of clevosaurs in the palaeo-archipelago. The larger reptiles on the palaeo-island do not exceed 1.5?m in length, including a small carnivorous crocodylomorph, Terrestrisuchus, and a possible example of insular dwarfism in the basal dinosaur Pantydraco.     

The effect of water on accessory phase solubility in subaluminous and peralkaline granitic melts

The solubilities of columbite, tantalite, wolframite, rutile, zircon and hafnon were determined as a function of the water contents in peralkaline and subaluminous granite melts. All experiments were conducted at 1035 °C and 2 kbar and the water contents of the melts ranged from nominally dry to approximately 6 wt.% H₂O. Accessory phase solubilities are not affected by the water content of the peralkaline melt. By contrast, solubilities are affected by the water content of the subaluminous melt, where the solubilities of all the accessory phases examined increase with the water content of the melt, up to 2 wt.% H₂O. At higher water contents, solubilities are nearly constant. It can be concluded that water is not an important control of accessory phase solubility, although the water content will affect diffusivities of components in the melt, thus whether or not accessory phases will be present as restite material. The solubility behaviour in the subaluminous and peralkaline melts supports previous spectroscopic studies, which have observed differences in the coordination of high field strength elements in dry vs. wet subaluminous granitic glasses, but not for peralkaline granitic glasses. Lastly, the fact that wolframite solubility increases with increasing water content in the subaluminous melt suggests that tungsten dissolved as a hexavalent species.     

Quaternary stresses revealed by calcite twinning inversion: insights from observations in the Savonnières underground quarry (eastern France)

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ₁ roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
